No, the hard lockup was caused by an endless recursion.  
ExtendedClipboardUnixInterface unexpectedly dispatched back to  
Clipboard which dispatched back etc. The Mac interface does not do  
such sillyness ;) I'll fix it shortly.

Now, in any case that *should* not cause a hard lockup but for some  
reason on the Linux VM it still did not react to Alt-. to break into  
the loop.

Ian, any idea? I have seen this before, but never took time to  
investigate. Actually I think it did happen on John's VM too but  
again, I'm not certain.
